Epoxy resin is poured and cured in a vacuum to form a high-strength fiberglass structure. The insulation grades are F and H. Epoxy resin dry-type transformers have the characteristics of good electrical performance, strong lightning impact resistance, strong short-circuit resistance, small size and light weight. A temperature display controller can be installed to display and control the operating temperature of the transformer winding to ensure the normal service life of the transformer.
